Among active studies in the research field of the photo-functional polymers composed of photoresponsive chro-mophores, we have developed various functional membranes composed of organic photochromic materials. As oneof wet and soft systems, which are controlled by light, we prepared a photo-responsive hydrogel thin layer, which wasattached covalently to the surface of a glass plate at one side through in situradical polymerization of N-isopropy-lacrylamide, acryl ester of spirobenzopyran and N,N-methylene-bis(acrylamide)on a flat glass substrate whose sur-face had been modified with vinyl groups. The influence of the light irradiation and the temperature change to thevolume of the photo-responsive hydrogel was analyzed systematically, and photo-induced micro-relief formation wasdemonstrated by using a micro-pattern projection system. As a result, it was observed that the hydrogel shrank inresponse to the light irradiation with the wavelength of 436 nm at any temperatures below 30℃, and the 3-D micro-relief was formed by micro-patterned light irradiation in a few seconds. Also it was proved that microchanel alongarbitrary pathway can be formed instantly by micro-patterned light irradiation in an “on demand”way. Further, weinvestigated photo-responsive behavior in water of photochromic polymers immobilized on quartz surfaces, by usinga quartz crystal microbalance technique with dissipation measurement (QCM-D technique), and extracted the photo-induced change in the characteristics of polymer-water interface.
